How To Download and Use This Control

  1. Make sure you have the latest version of EZ-Builder installed.
  2. Select the Install button below to download the file.
  3. Double click the downloaded file to open installer.
  4. The installer will add this control to EZ-Builder.

Control the UBTECH Alpha Robot Digital Servos (UBT-12HC) with EZ-Builder. The servos must be powered appropriately, and connected to the EZ-B v4 or IoTiny with the respective port. Visit the Config menu of this plugin to view the port configuration.

The Virtual Ports (V0..V99) in EZ-Builder can be assigned to the UbTech servos.

- This plugin requires the RX signal wire of the servo be connected to TX of the selected UART or digital port (if Software UART is selected)

- Hardware UART is available on the EZ-B v4 only, and is recommended if using an EZ-B v4. View the EZ-B v4 datasheet to identify the UART ports (0, 1, or 2). Datasheet can be found here: http://www.ez-robot.com/Tutorials/Lesson/18?courseId=4

- Software UART is available on both the EZ-B v4 and IoTiny

- The configuration menu also provides an option to select the Virtual Ports, which correspond with the ID's of the UBTech servos. If the UBTECH servo ID #0 is connected, select V0. #1 = V1, #2 = V2, etc..

- Default baudrate of UBTECH servos is 115,200

OK. There are  many  people working on that issue and information in that link.

Geez that robot looks fairly tall and fast in a youtube demo ,wondering if it could still be hacked to be even taller without effecting the center of Gravity (The arch enemy of all tall robots).
Oh wait no that's just a camera trick I saw,put the camera Low down and you can make any robot look Gigantic. I saw another video that showed JD in the background about the same height so it does look like there is a height barrier to getting a tall one at a reasonable price unless you design one for yourself that is.

Hi, robo rad, the exact height of alpha 1S is 398 mm (ubtech specs). servo speed and torque are similar to usual servos (0.198 s  x 60,  12 kg.cm at 8.5 V).
But it performs high speed and stability. What's the secret ? Probably the sophisticated design of the control system, taking in consideration  weights, inertia,etc. for that specific mechanical structure.
I made a 720mm tall robot , similar to JD, simply actuating powerful  servos (Hitec HS 805BB) as required, but it's much slower and unstable !
I am students from indonesia, i have read your command in forum" how to control UBTECH servo's 12 HC for Alpha 1s, can you help me show to control them, i need this to do my project, so that i can finish my bachelor education.

thank you for attention
